我有包含結構化條目的期刊書目的 OCR 文本。我想使用Invisible XML標準來提取和決議條目。

iXML 語法
data: entry .
entry: -#a, entrynum, " " , content .
entrynum: -digit .
digit: ["1"-"9"] .
content: ~[] ; -#a .
對 iXML 語法的最初嘗試產生了模棱兩可的決議（使用CoffeePot iXML 處理器）。

首先，我想了解如何對條目進行分塊，然后開始決議內容：例如，每個條目編號后跟一個或多個空格，然后是字母數字標題，后跟句點等。
uj5u.com熱心網友回復：
“也許。” iXML 的一大優勢是它可以處理歧義。這使得語法更容易撰寫。如果模棱兩可的選擇同樣有效，或者您不在乎選擇了哪個模棱兩可的選擇，那么它的效果非常好。
對于書目資料，我懷疑某些選擇比其他選擇更有效，您確實關心選擇了哪個選擇，這使得它更難。我還打賭，由于 OCR 不完善，因此存在很多歧義。
我認為單個 iXML 語法不會決議輸入并準確生成您想要的輸出，但它可能會構成一些更廣泛策略的有用部分。我首先嘗試將參考書目分成單獨的條目，將語法限制為單個條目。然后我可能會看看我是否可以計算出不同類別的條目（書籍、雜志、期刊等），并且每個條目可能有不同的語法。
祝你好運！

你的語法非常非常模棱兩可，因為“~[]”包含#a，所以決議輸入的方式有幾十種。您必須確定如何明確識別條目的開頭，如果這是“如果它以數字開頭”，那么您還必須防止以數字開頭的行被識別為“內容”，例如，
content: line .
line: ~["0"-"9"], ~[#a]*, #a.
如果您想追蹤歧義，可以嘗試我的實作（https://homepages.cwi.nl/~steven/ixml/tutorial/run.html），它比 Norm 慢得多，但提供了有關源的潛在有用資訊的歧義。
這是您的內容的合理第一次嘗試，但請注意，內容中的唯一 1994 被視為條目號：
ocr: entry .
entry: numbered, unnumbered*.
-numbered: number, (line*; -#a), blank-line.
-blank-line: -#a.
-line: ~[#a] , -#a.
@number: ["0"-"9"] , -" ".
-unnumbered: ~["0"-"9"; #a], line , blank-line.
